Logarithms
Logarithms were invented by John Napier as another form of writing indices.
The rules of logarithms
1. Use your calculator to find:
From your answers suggest a simplification for log a + log b
2. Use your calculator to find:
From your answers suggest a simplification for log a - log b
3. Use your calculator to find:
From your answers suggest a simplification for nlog a
Change of base rule
Start with x=
Write as an index
Take a log of both sides
Use the power rule
Leave x on it’s own.
